Once again, I find myself checking over the UTF-8 validation code in websocket-driver, and once again I find I cannot ever remember how to make sense of this regex that performs the validation.

Being paleo is like paying a stupidity tax. Again, it’s not you who is stupid, but the diet sure is, because it lets you drink paleo coffee while putting paleo butter and paleo syrup on your paleo waffles before you drive your paleo minivan to the paleo office to sit in your paleo cube and do spreadsheets on your paleo computer.

That is scientology-level stupid.
